	Hello. I catch periodic random freezes/hangs, more often in games, rarely at desktop workspace mode. Card radeon 7970. driver amdgpu tell about freezes. try with another driver "radeon", problem repeated, with another logs and behavior. Well...I sell my 1600 CPU and buy 3500. And problem appear again! Problem will disappear, if change videocard slot to bottom PCIE4: x4. because at first, I blame integrated pcie controller in processor. But with CPU change - problem still exist... I tried another kernel version - without success. 4.12, 4.18, 4.19,5.2,5.3 ... It definitely not videocard problem, because in old platform at AM3 socket (and FX8320) this problem not exist, with same drivers(versions) and videocard. No thermal issue, no furmark long load freezes. MB: Asrock B450 Pro4 ATX. BIOS version 3.60 now. RAM AMD Radeon R7 Performance Series [R748G2606U2S-U] 2* 8Gb (tested with memtest many times, without errors) I contacted to Asrock technical support, approximate one month ago, but nobody answer me. Please, help me about solution.
